Pursuing along with GraduationThere is no restriction with regard to pursuance of CS FP (company secretaries foundation programme) level along with any other course i.e. any graduation course or diploma course. It is designed for being pursued along with Graduation after their 10 + 2 (senior secondary/intermediate).
A student on passing the CS FP level would be taking up the CS EP level. The course at the both these levels can be pursued along with graduation/post-graduation courses.
Pursuing along with B.Sc | B.Tech | M.B.B.S | ...Since the course is basically commerce oriented, the best bet is a student doing this course along with formal B.Com course of any university.
However this is not a requirement/compulsion. Even students doing their Graduation course in the science stream, can pursue this course along with their graduation (i.e. B.Sc). Even students doing engineering, medicine etc can also pursue this course along with their graduation courses.
These would be useful to those who are capable of building their own enterprises in their profession like corporate hospitals etc.
